Is this the page for the breakout board : http://www.e-gizmo.com/KIT/tri%20axis.htmlThe sensor is the KXPB5, made by kionix.This is the page on the Kionix website: http://kionix.com/accelerometers/kxpb5So it is a sensor with analog outputs, and it needs the 3.3V of the Arduino board as power supply.

I suggest to read the datasheet (twice) to try to understand how the pins should be connected.

If the photo in your first post is the breakout board you have, you have the version with the analog outputs.This pins are shown in Table 4 of the datasheet.VDD = 3.3V (the sensor is made for 3.3V but also 5V is allowed)GND = GNDVmux : this is a outputs, don't connect it.S0, S1, Aux_in, PD, ST : connect to ground.X_output, Y_output, Z_output : connecto to three analog inputs of the Arduino, like A0, A1, A2.

Next time, if you want to buy a sensor, check out these sites: - http://www.sparkfun.com/ - http://adafruit.com/

You could use the on-chip multiplexer if you are running short of analog pins - 2 digital pins to S0 and S1 enable you to route x,y or z to the Vmux pin - so only one analog pin then needed. That or just use 3 analog inputs for x,y,z.

Yes its very similar to the ADXL335 except that the sensitivity is 660mV/g instead of 330mV/g (that's at 3.3V - it will be 1V/g at 5V supply since its ratiometric).
